Strafe RGB Mk2 - Default (onboard) profiles no longer working?

As of today, when my PC is turned off (so no ICue running), my entire keyboard is unlit apart from the very top row of buttons/lights (for profile, brightess, numlock etc). None of the actualy keyboard keys are lit at all!

If I press the profile button nothing changes, apart from that top row.

I've re-applied the latest firmware to the keyboard. Cleared it. Ensured I'm on the latest ICUE. Reload lighting effect after light effect to the three onboard slots, but when I turn my PC off, my keyboard goes unlit (apart from the top row).

What's caused this? Normally I just have a simple white layout across all the keys as a default. Why is this no longer working?

ps: I've pressed the brightness button and can see the lights on the top of the keyboard changing brightness.

Tried a complete reset of the keyboard via unplugging it and pressing ESC and replugging it back in.

Three default lighting effects are then available.

When I attempt to overright one of the onboard effects with a static colour one, I get back to only the top row being lit up, and all actual keys being unlit.

Restarted froom scratch. Created a whole new profile. Uploaded that and it works.

My old ones no longer do...

Grrr....

At least the default profile(s) are working again!
